A flexible and scalable, fully software-based lock-in amplifier for nonlinear spectroscopy
Daniel Uhl, Lukas Bruder, Frank Stienkemeier
We demonstrate a cost-effective, fully software-based lock-in amplifier (LIA) implemented on a commercial computer. The device is designed for application in nonlinear spectroscopy…

Unravelling the Full Relaxation Dynamics of Superexcited Helium Nanodroplets
Jakob D. Asmussen, Rupert Michiels, Katrin Dulitz +20
The relaxation dynamics of superexcited superfluid He nanodroplets is thoroughly investigated by means of extreme-ultraviolet (XUV) femtosecond electron and ion spectroscopy comple…

Single-shot electron imaging of dopant-induced nanoplasmas
C. Medina, D. Schomas, N. Rendler +19
We present single-shot electron velocity-map images of nanoplasmas generated from doped helium nanodroplets and neon clusters by intense near-infrared and mid-infrared laser pulses…
